Battery module

The utility model relates to the technical field of batteries, in particular to a battery module, which comprises an upper-layer cover plate, a lower-layer cover plate and a battery pack fixed between the cover plates, and is characterized in that the cover plates are provided with radiating fins, heat-conducting silicon wafers are arranged between single batteries of the battery pack, and the upper surface and the lower surface of each heat-conducting silicon wafer are respectively tightly connected with the cover plates. And the upper and lower aluminum alloy cover plate structures are tightly attached to the surfaces of the single batteries, so that the temperature equalization effect is achieved on each grouped single battery, and the external heat dissipation effect of the single batteries is also enhanced. In the process of stacking the single batteries into groups, the heat-conducting silica gel pads arranged at intervals not only provide buffering of group extrusion stress for the single batteries, bu
